Glitnirhad
Glitnirhad is a fictional planet featured in the science fiction series "The Expanse" by James S. A. Corey. It is the third planet in the Sol system, orbiting between Mars and Jupiter. Glitnirhad is known for its unique geological features and its role in the series' plot. The planet is home to a vast, ancient ocean that covers most of its surface, with a few small, scattered landmasses. Its ocean is rich in minerals and resources, making it a valuable location for mining operations. Glitnirhad's atmosphere is primarily composed of nitrogen and oxygen, similar to Earth's, but it is thinner, leading to lower gravity. The planet's most notable feature is the Glitnirhad Crater, a massive impact crater that spans nearly half of the planet's diameter. This crater is believed to have been caused by a catastrophic collision with a large asteroid or comet billions of years ago. The impact created a massive chain of mountains and valleys that encircle the crater, and it is home to a diverse range of ecosystems, including unique forms of life adapted to the harsh conditions. Glitnirhad plays a significant role in the series, serving as a key location for several plot points and character developments. Its resources and strategic importance make it a target for various factions, including the United Nations Mars government, the Belt Alliance, and the Outer Planets Alliance. The planet's unique features and its role in the series make Glitnirhad an intriguing and memorable addition to the "The Expanse" universe.
